5 Promising Secure Team Chat Apps to host on your server

With prolonged lockdown measures in place to prevent the spread of coronavirus, businesses are relying on dedicated messengers to keep in touch with their employees while they work from home. Of course, there are plenty of commercial options available, but these are not always the best solutions.

Throughout the COVID-19 pandemic, there has been a distinct increase in digital footprints. Not only does this mean that there is more information for internet service providers to eavesdrop on, it has prompted a rapid rise in cybercrime with messengers at the center.

Whether you want to secure your team’s conversations, or simply want to explore a more customizable experience, we recommend considering self-hosted options that install directly onto your own server.
